Which depth?

Looking to order a pair of carbon clincher wheels in the next fortnight or so.
i will decide on my requirements then either find a pair or go with some hand builds.
I am tossed up between 38mm and 50mm. these will be for my summer bike and will not be changed unless i purchase some Shimano R501s or something later on in the season.
it can get pretty breezy down in Devon at times and i am worried 50mm will make it impossible to ride, however is there that much difference and surely 50mm has much much more aero properties and are theoretically stiffer due to a shorter spoke length??
Any suggestions?
Many thanks

I'd only compromise with a 38mm if you're considering doing frequent long climbs, otherwise just get 50mm. The deeper ones are of course more aero, make it easy to maintain a constant speed and sound a lot better too.
Deep sections aren't that difficult to control, it's just the strong gusts of winds which'll get you. Careful on descents too, if it's windy. This is where your handling skills will come in handy. There has been a times where I've had to ride at a 30* angle due to strong side wind with my 60mm F6R's.
Most importantly though, refrain from racing or doing group rides when it's windy with them.
Or taking it out on days like this: http://www.youtube.com/watch?v=H8qgjyqi ... &index=1990 -
Climbing!! i live in Sevon so it is from one hill to the next so would you suggest 38mm then? something like a Zipp 3030
-
I would just go for 50mm
Climb fine in my experience and look great
I don't find much advantage with my 38's over standard rims0 -
The deepest i have used are Easton EA50 SL (31m) why do people say that a deeper rim is not as good on a climb? if i went 50m i could get to new Shimano C50's!?!?!0

The 50mm deeps are a bit heavier so not the climbing wheel of choice.
However in practise they are fine.
I wouldn't get too concerned unless you are looking for marginal gains on your way to getting an elite license0 -
My bike is currently at 4.5kg so i not worried a bit if they are slightly heavier than the 38mm. Many thanks The c50s it is then!0

For everyday riding I'd go for 38mm, and tubsI'm sorry you don't believe in miracles0

Not it’s not.
Zipp 303’s are 45mm deep btw.0 -
Two points:
1) I've never had an issue with my 50mm rims in the wind, I've heard the stories, but maybe it's only particularly noticeable above 50mm ?
2) Shimano R501s have sh!te bearings. I bought a pair for the turbo trainer and they make a terrible noise, even after re-greasing.Science adjusts it’s beliefs based on what’s observed.
Faith is the denial of observation so that Belief can be preserved0 -
Maybe the wrong choice of wheel if you'll spend most of your time going uphill?0
-
4.5kg without any wheels, cassette, chain or a chainset!
and there are s lot of hills but then there are also a lot of down hills. when finished i will think it will weigh about 4-8kg, am going to look at some C50s today!0 -
Im 78kg
Without my arms, legs and feet0 -
Ment to type 7-8kg0

Have you worked out how to go around pot holes yet? the advice in the other thread was spot on, not the bit about glasses but get some tough hand builds if you love destroying wheels...
but go 50, they'll look the best.0 -

I ride 60mm all carbon clinchers, they look good, roll well and handle well, its just a matter of handling.I don't mean to brag, I don't mean to boast, but I'm intercontinental when I eat French toast...0

Also in devon and riding across the moor when it's windy even with a 38mm rim is not fun, 50mm would be scary.ARTHUR

All least someone has experienced and relate to it, it can get pretty gusty around Princetowngaddster wrote:Also in devon and riding across the moor when it's windy even with a 38mm rim is not fun, 50mm would be scary.0
